The HPD (High Power Direct) motor was developed by Werner Eck and is distributed by Flytec.
It is a brushless, rotating-can motor which directly powers a 1.4 m diameter folding-blade propeller, with no reduction gear.

An advanced control system prevents accidental motor activation. If essential parameters are exceeded, the power supplied is automatically reduced, and the pilot is informed of the problem by means of an error message on the control interface.

The motor's functioning is constantly monitored by an interface that displays all operational parameters, such as voltage, power in amp-hours, current absorption, motor temperature, the Motor Management System, the state of the accumulators, and so forth.

The standard accumulator is a 24 Ah lithium ion model, providing a flight time of about 20 minutes with an RX18 or RX21 wing and an 80 kg pilot.

Two batteries connected in parallel (48 Ah) provide a flight time of 40 minutes.

Using a modern rapid-charge lithium polymer accumulator, flight time can be extended to about 30 minutes, or up to one hour's flight when two of these accumulators are connected in parallel, providing a total of 80 Ah.

The maximum flight time varies according to pilot weight, the style of flying, and the surface area of the wing.
